Enterprising businesses get to Red Hat Storage Days!

By E.G. Nadhan, Chief Technology Strategist, Red Hat

As businesses are increasingly being asked to cope with burgeoning amounts of valuable data, there’s a data explosion in the enterprise. This explosion fuels the need for a new approach to storage, which is the underlying theme of Mark Thiele’s article, 400 million new servers needed by 2020 — Think different or lose. “You aren’t ready to scale the way you’re going to need to scale,” he contends, noting that data sources are projected to reach 30 to 50 million by 2020. In his article, Are 18-month org charts and constant training the new reality of IT?, Curt Carver agrees, saying, “To plan for an IT future, you’ve got to be agile….”

So the drumbeat is growing louder: Digital enterprises need storage solutions that are agile and continuously evolving to accommodate dynamically changing requirements.

What’s an enterprising business to do?

To meet contemporary storage challenges head on, digital enterprises of the future should embrace open source and all it enables. To that end, Red Hat GM for Cloud Product Strategy, Bryan Che, penned an article titled, Open source is programming the digital future, noting that innovative companies like Uber and Facebook have embraced a digital approach to help ensure their long-term viability. Che’s article highlights the role of open source in this evolution as it contributes to the creation of new categories of functionality across enabling technologies.

Latest release of Red Hat Gluster Storage enhanced with container support, file-based auto tiering, writable snapshots, and more

By Alok Srivastava, Senior Product Manager, Red Hat Gluster Storage and Data, Red Hat

Red Hat Gluster Storage 3.1.2 became generally available today, adding such key functionality as containerization and file-based auto tiering to its already feature-rich base. For detailed information on all the latest Red Hat Gluster Storage features and enhancements, see the documentation and read on here. For my interview on the topic, watch our video below.

 

 

Key feature enhancements

 

Red Hat Gluster Storage image on Red Hat’s container registry for persistent file storage for containerized applications

Persistent file-based storage from containerized Red Hat Gluster Storage can be consumed by containerized applications over the network (see following figure). You can quickly bring up a Red Hat Gluster Storage container in a Red Hat Atomic Host or on Red Hat Enterprise Linux by simply pulling a Red Hat Gluster Storage image from Red Hat’s container registry.

 

RHGS 3.1.2 (1)

 

File-based auto tiering to leverage innovation in flash and HDD design

The file-based auto tiering feature of Red Hat Gluster Storage 3.1.2, initially available only in tech preview and supported on Red Hat Enterprise Linux 7 based on Red Hat Gluster Storage, places frequently accessed or “hot” data on fast media (e.g., flash, SSDs) and seldom-accessed or “cold” data on higher capacity yet slower-spinning media (see following figure).

 

RHGS 3.1.2 (2)

 

Tiering combines SSDs and HDDs to enable intelligent data placement and thereby boost performance and cost efficiencies. For example, a new or an existing volume may be distributed (erasure coded) on HDDs and the hot tier could be distributed on SSDs. The “attach” operation of tiering, transparent to applications, converts existing volumes into a cold tier. Together, the combination is one tiered volume.

 

Writable snapshots with shared backend LVM store

This release of Red Hat Gluster Storage supports writable snapshots–clones of snapshotted volumes with read/write permissions. Until today, only thin, LVM-based, read-only snapshots were available in the product. The writable clones, which are space efficient and instantly created, share the backend LVM store with their parent snapshots (see following figure).

 

RHGS 3.1.2 (3)

 

Other feature enhancements

 

Bit rot detection status

The bit rot detection functionality in Red Hat Gluster Storage periodically scans all data bricks in the product, compares checksums, and identifies and sometimes proactively fixes corrupted files. This release augments this feature so that you can identify corrupted files easily and take any necessary corrective action.

Faster SMB access

SMB shares back-ended by Red Hat Gluster Storage now perform better for streaming workloads. With this release, asynchronous IO from Samba to Gluster is supported and the relevant option is enabled by default in smb.conf. We have seen up to 100% performance increase from the previous release in our performance labs!

Offline console installation

Offline installation of the Red Hat Gluster Storage console is now enabled by offering an OVA image. You can now import RHGS-C OVA image to Red Hat Enterprise Virtualization Manager and install the console s/w on virtual machines.

Red Hat Gluster Storage now available in Google Cloud Platform

By Sayan Saha, Head of Product Management, Red Hat Gluster Storage and Data,
Red Hat

Today we announced the availability of Red Hat Gluster Storage in Google Cloud Platform as a fully supported offering. Red Hat Gluster Storage will give Google Cloud Platform users the ability to use a scale-out, POSIX-compatible, massively scalable, elastic file storage solution with a global namespace.

This offering will bring existing users of Red Hat Gluster Storage another supported public cloud environment in which they can run their POSIX-compatible file storage workloads. For their part, Google Cloud Platform users will have access to Red Hat Gluster Storage, which they can use for several cloud storage use cases, including active archives, rich media streaming, video rendering, web serving, data analytics, and content management. POSIX compatibility will give users the ability to move their existing on-premise applications to Google Cloud Platform without having to rewrite applications to a different interface.

Enterprises can also migrate their data from an on-premise environment to the Google Cloud Platform, easily leveraging the geo-replication capabilities of Red Hat Gluster Storage.

A Red Hat Gluster Storage node in Google Cloud Platform is created by attaching Google standard persistent disks (HDD) or solid-state persistent disks (SSD) to a Google Compute Engine (GCE) instance. Two or more such nodes make up the trusted storage pool of storage nodes. To help protect against unexpected failures, the Red Hat Gluster Storage nodes that constitute the trusted storage pool should be instantiated across Google Cloud Platform’s zones (within the same region), up to and including a single zone.

Gluster volumes are created by aggregating available capacity from Red Hat Gluster Storage instances. Capacity can be dynamically expanded or shrunk to meet your changing business demands. Additionally, Red Hat Gluster Storage provides geo-replication capabilities that enable data to be asynchronously replicated from one Google Cloud Platform region to another, thereby enabling disaster recovery for usage scenarios that need it in a master-slave configuration.

Anticipated roadmap features like file-based tiering in Red Hat Gluster Storage include providing the capability to create volumes with a mix of SSD- and HDD-based persistent disks providing storage tiering (hierarchical storage management) in the cloud in a transparent manner.

Red Hat Gluster Storage in Google Cloud Platform will be accessed using the highly performant Gluster native (Fuse-based) client from Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, and other Linux-based clients. Users may also use NFS or SMB.

We are excited that users will be able to take advantage of all the Red Hat Gluster Storage features in Google Cloud Platform, including replication, snapshots, directory quotas, erasure coding, bit-rot scrubbing and geo-replication, because they now have a compelling option for their scale-out file storage use cases in Google’s cloud.

The importance of partners

As we approach the holiday season, our latest partner announcement is appropriate. Why? Because, partner-wise, Red Hat Storage is setting up for a veritable feast.

Storage is an ingredient, not a meal

Let’s face it. Nobody ever deploys storage technologies by themselves. They’re always deployed alongside hardware platforms and workloads–they have to be. Without hardware platforms to run on top of and applications needing their services, storage technologies don’t really do anything.

Why Software Defined Storage is set to disrupt the world of containers. And why you should care.

Containers have the potential to be hugely disruptive – they are about to impact almost every process and person within the data center. Container technology will also impact how we think about storage for applications and microservices. In turn, software defined storage will impact how storage is dynamically provisioned and managed for containerized applications.

Latest OpenStack user survey shows Ceph continues to dominate

According to the OpenStack Foundation’s sixth and most recent user survey released just prior to this week’s OpenStack Summit in Tokyo, 62% of users selected Ceph RBD block storage for their OpenStack use cases, nearly three and more than four times the two closest alternatives, LVM (default) and NetApp, respectively.  In production, a full 38% of respondents indicated that their OpenStack deployments depended on Ceph as their Cinder driver, with the same comparisons. A survey of the largest production clouds, those exceeding 1,000 cores, showed similar results, with 37% of users selecting Ceph RBD followed by NetApp at 12%.  Interestingly enough, with 9% of respondents using GlusterFS in production, development & quality assurance, or proof of concept across all OpenStack deployments, more than 70% of OpenStack users are relying on block storage championed by Red Hat Storage.
